I am having an issue with cflayout area's and the
ColdFusion.Navigate function. But after researching my issue, it
looks like it's more a CFGrid problem. Below is code that just
loops through and writes out 20 simple grids. But as CF is writing
them out, on the 16th one or so it gives me a javascript error,
"Invalid procedure call or argument". Is there anyway to get around
this and have many grids on a page, or is this just an error that
we have to deal with? The real issue arises for me when I have
multiple links that navigate a layout area to different pages that
each have their own cfgrid in them. It's like it's holding history
though, because on the 12th or so link, it always gives me that
error.

I don't use the new CF tags, but I've been using Extjs 1.1
for a recent project. While there may be some internal limit
imposed by CF, I think that 20 is way too many grids for a page and
I think the web page will choke trying to display everything. I'm
finding that the extjs grid really bogs down the browser when
handling large grids and seems to consume large amounts of
resources in general.
